How has 500 Kendall Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 500 Kendall Street, covering report years 2015–2024. Its ENERGY STAR score went from 61 in 2015 to 72 in 2024 (+11 points); its best year on file was 2020, at 86. Site EUI moved from 87.8 kBtu/ft² (2015) to 68.1 kBtu/ft² (2024), a 22% decrease. Reported emissions went from 2,174 tCO₂e to 1,640 tCO₂e over the same span (down 25%).
What does an ENERGY STAR score of 72 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 72 means the building performs better than about 72% of its national peers. BuildingCensus bands the score into report-card grades; 72 falls in band B — above median (70–84). It sits 3 points below 75, the threshold for ENERGY STAR certification. In Cambridge, 50% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. 500 Kendall Street's 68.1 kBtu/ft² across 349,325 sq ft works out to about 23.8 billion Btu (6,972 MWh-equivalent) in 2024. Its source EUI of 141.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,837,780 kWh of electricity, 11,778 therms of natural gas and 4,306 thousand gallons of water for the year.
Which law requires 500 Kendall Street to report its energy use?
